[1000mp] FT1000MP 10m out?

[HA3LN]

Hi,

I'm just preparing for the EU-HF and after one band change the 10m went
deaf.
There is no difference between the empty antenna port and the one which is
the
antenna is connected to.

I've tested the other bands but the rest are OK. 10m antenna line is OK on
R2 (FT857D).


Is that possible that only the 10m goes off?
What can be the reason? 


Thanks and 73!
